SEALING-MACHINE.

Original application filed February 26, 1914, Serial No. 821,239. Patent N 0. 1,134,070, dated March 30, 1915.

Specification of Letters Patent.

Divided and this application filed February 25, 1915. Serial No. 10,525.

To all whom it may concern:

Be it known that I, ROBERT MAGRANE, a citizen of the United States, residing at New York, in the borough of Queens and State of New York, have invented new and useful Improvements in Sealing-Machines, of which the following is a specification.

This invention relates to scaling mechanism or capping machines and has particular references to dies and their operation. The present application is a divisional application divided from a co-pending applica-' tion filed February 26, 1914, Serial No. 821,239, issued March 30, 1915, as Patent No. 1,134,070, and certain features hereln disclosed but not claimed are claimed in a co-pending application Serial Number 871,732 filed November 12, 1914.

One object of the present invention is to simplify the sealin die construction and operation; another 0 ject is to provide a machine that will seal a metallic closure to a glass receptacle without danger of breaklng the latter, and still other objects will appear in the following description and claims.

Referring to the drawings:

Figure 1 is a side elevation of a part of the mechanism showing a sealing chamber and valve; I

Fig. 2 is a plan showing the valve timing mechanism;

Fig. 3 is a side elevation in section taken on the line 33 of Fig. 2;

Fig. 4 is a sectionalelevation of the power cylinder and a vacuum chamber taken on the line44of Fig. 2;

Figs. 5 and 6 are elevations, partly in section, of the mechanism for closing the vacuum'chambels; and

Fig. 7 is a detail showing the manner of locking the sealing chamber.

While the machine disclosed is adapted to seal containers in a vacuum, those features of the apparatus do not form part of the present invention but are claimed in the 'co-pending application referred to.

In Figs. 1 and 4, a vacuum chamber is shown as formed by a cup-shaped cylinder 10 which is closed at the bottom by a plug cap 11 and is carried within a circular flange 12 forming a part of the table bed 13. .The cylinder 10 is equipped with a shoulder 14 and a threaded portion 15 by which, to-

gether with the collar 16 and nut 17, it is attached to the table bed. Within the cylrespective closures applied simultaneously and by the same common mechanism although the closures may be operated successively if desired.

As shown in Figs. 2 and 4, the caps or f closures 19, 19 are both attached tothe ends of a thin somewhat elastic beam 25 which is pivoted at its center in a manner to be described. The movement of the caps and the beam in opening the chambers is first vertitically upward until the closures are clear of the chambers, and then the caps rotate with the beam 25 in a clockwise direction for a distance of degrees, the caps and the beam then being in the position indicated at 25 and 19 in Fig. 2.- The closing movement takes place in reverse order.

The construction producing this move ment is best shown in Figs. 3, 5 and 6. As shown, the beam 25 is carried by a head 26 which is pinned to a tubular shaft 27. The

shaft 27 has both a vertical and a rotary mo- .tion within a bearing sleeve 28 clamped to the table bed 13 by a nipple 29. Two diagonal cam slots 30, 30 diametrically opposite each other are formed in the shaft 27, and also two straight longitudinal slots 31, 31 are formed at its lower end. The shaft 27 is further provided with two shoulder tracks 32, 32, two extensions 33, 33 and a clamp 34 for the extensions. The nipple 29 carries at its lower end a guide sleeve 35 which is equipped with two longitudinal parallel slots 36, 36,

and at its lowe end is fitted with two rollers 37, 37 locate opposite each other.

As shown in Fig. 3, a pedal 38 is fulcrumed at 39 to the frame 40 and is adapted to move the rod 41 downward against the.

tension of springs 42, 42 when it comes into contact with the collar 43 carried by 5 cap is replaced. The chambers have their 1 the rod. An auxiliary spring 14 tends to hold the pedal upward.

The upper end of rod 41 enters the tubular shaft :27 and is equipped with a head 15 which carries a fixed shaft 16 upon which are mounted two pairs of rollers 17, 47 and 48, 4:8. The rollers 47, 47 engage the diagonal slots 30, 30 while the rollers 48, 48 enga e the slots 36, 36.

W ien the chambers are open, and the closures are in the broken line position shown in Fig. 2, the springs 42, 12 main tain the rod 11 and its head 45 in their uppermost position, in which position the rollers 47, 47, 418, 48 are in the upper parts of their respective slots 30 and 36. In this positionthe shoulder tracks 32 at the :lower end of the tubular shaft 27 rest upon the rollers 37.

The chambers are closed by depressing the pedal 38 which carries the rod 41 downward as described. The rod and the head 45 :cannot rotate as the rollers 48, as attached thereto travel in the vertical slot guides 86, 36. The initial movement of the head 45 downward however operates upon thediagonal slots 30, 30 in the tubular shaft 27 and rotates the shaft 27, beam 25 and closures 19 in an anti-clockwise direction 90 degrees, in which position the closures are directly over the chambers. The shaft 2-7 and closures carried thereby are prevented from downward movement during this rotation by the shoulder tracks 32, 32, which are at thistime riding on the rollers 37, 37 which support shaft 27 during this part of its movement. When the shaft has rotated 90degrees the rollers 47, 47 have reached thebottoms of slots 30, 30; and the shoulder tracks 32 have run off their supporting rollers 37, 37 so that the further movement of the head 45 carries downward with it the shaft 27 and the closures carried there by. During this downward movement of the shaft and closures any rotation is prevented as the straight open slots 31, 31 in the lower part of the shaft are engaged by the rollers 37, so that the closures move dire'ctly i downward upon their respective chambers.

It will be seen that a single depression of the pedal will cause the closures first to swing through an arc of 90 degrees to a position directly over the chambers and then to move directly downward to seal the chambers, and also when the closures are permitted to move upward, they will move directlyupward until they clear the chambers and then swing backward 90 degrees to the first position. t

The particular methodof sealing the receptacle that is indicated at w, m in Fig.4 is'by applying a metallic cap indicated at y in the same figure equipped with an annular beading inclosing a gasket and by squeezing the gasket against the container to form the seal. A sealing cap of this type and a machine for applying the cap is disclosed in Patent No. 874,201 issued to J. V. Hull, December 17, 1907,to which reference may be made. As indicated in Fi l, the cap 1 is provided with the metal ic beading 2 within which the gasket to be squeezed is located. To effect the squeezing, pressure is brought to bear upon the beading vertically, as described in the patent referred to, by annular jaws located above and below the beading. In machines of the prior art in which such scaling is effected, the lower jaw has necessarily been made sectional, as the receptacleand cap have been inserted in the chamber either through the sideorbottoln of the chamber, so that the beading has to clear the lower jaw both before and after sealing.

This sectional and costly construction of the lower jaw is eliminated inthe present machine byproviding the described chamber and its cap-like closure. This improved construction permits the lower jaw to be formed simplyof a hardened steelannular member, shown at 50 in Fig. 1, which is carried upon an inner shoulder of the piston 18. A coacting annular jaw formed likewise of a single piece of turned steel is mounted upon the undersideof thecap 19, as shown at 51 in the same-figure. A further advantage of this construction is. that it permits the easy change of jaw ringsso that thcmachine may handle different sizes of sealing caps, whereas informer types of machines the substitution of an entire sealing chuck is necessary when the size of the ca s is to be changed.

his method of mounting the sealing .jaws requires the locking of the closure cap 19 to the chamber 10 so that the cap will withstand the thrust of the sealing pressure. For this purpose any suitable lockingmeans may be employed. Thatshown in the present instance, in FigsLQ, 4 and 7 is fully described in the Patent No. 1,134,070 referred to above.

As best shown in Fig. 4:, the support for the lower ring die is chambered so as to allow the insertion of the receptacle within the support and withinthe lower die 50. The upper ring die 51 is supported by a disk 19 which reduces to a minimumlthe dead space above the receptacle and closure, this being of great advantage in sealing with a vacuum.

Power for operating the sealing mechanism may be derived from various sources, and the mechanism may be variously constructed. 1n the present machine, the force ofatmospheric pressure operating against a vacuum is utilized to produce the power to operate the sealing mechanism; but these features form no part of the present invention, and are fully described in the copending application referred to.

I claim:

1. In a sealing device for receptacles adapted to compress an annular beading on a closure to form a side seal against a substantially incompressible side wall of the container, said device comprising an integral sealhg die rin through which the receptacle 1s adapte to extend and upon which the bead of the closure is adapted to rest, an upper co-acting die adapted to engage the upper portion of said bead, and means to move said dies relatively under suflicient pressure to flatten the bead and compress the same to squeeze a suitable gasket between the bead and the side wall of the container to effect the side seal.

2. In a sealing device the combination of an integral annular die member adapted to encircle the container to be sealed, said annular die member having a sealing face adapted to engage the closure to be operated upon, an upper die member arranged for cooperation with said annular die member, said upper die member having a sealing face adapted to co-act with the sealing face of the annular die member to deform the closure independently of the container and means for effecting relative movement of said die members to permit insertion of a container intermediate them and within the annular die member.

3. In a device for sealing closures to containers in combination a pair of co-acting annular die members each of integral structure, said die members being provided with opposing sealing faces adapted to engage a closure positioned between them, means for effecting separation of said die members to permit the insertion and removal of a container through one thereof, and means for effecting relative movement of said die members to deform the closure independently of the container.

4:. In a device for sealing closures to containers, in combination, an integral die member provided with an aperture for the reception of a container, said die member being provided with a continuous sealing face extending about the aperture, a second die member disposed to cooperate with said integral die member to engage a closure, and

means for effecting relative movement of said die members to permit the insertion of a container in the aperture of the integral member, and to compress a closure thereon.
